Questions Arise About Jackson's 'Lethal' Dose, Death Timeline

When unsealed documents released this week stated that Michael Jackson died of a "lethal" dose of the powerful anesthetic propofol and that Dr. Conrad Murray waited 80 minutes to call 911, most thought the case was cut-and-dry. Some experts, however, are beginning to question things based on the numbers and timeline given in the documents. Details After the Jump

In a Los Angeles Times feature, several medical experts discussed their feelings about the details of the Jackson report, which stated that Dr. Conrad Murray administered 50 milligrams of propofol to Jackson on a nightly basis for some time. Murray told police that on the day Jackson died, he only gave the King of Pop 25 milligrams. Both the 25 and 50 milligram doses are nowhere near enough to kill a person, doctors who spoke with the Times said.

"It doesn't make any sense... I cannot believe that was the number that was given. Such a small amount won't tip anyone over in terms of respiratory depression," Dr. John Dombrowski, a member of the American Society of Anesthesiologists, told the Times.

Dr. Conrad Murray, who was Michael Jackson's cardiologist, has been a primary person of interest in Jackson's death investigation. Murray has admitted to law enforcement that he administered the drug propofol to the singer. The powerful anesthetic is reportedly what killed Jackson.

Murray was at Jackson's house on the day that he died. According to new documents, he left Jackson to make some phone calls, and when he returned, the King of Pop was not breathing.

Another one of Jackson's doctors, dermatologist Arnold Klein, has also faced speculation that he may have provided the music legend with illegal prescription drugs. He has denied any involvement in Jackson's death.

Jackson's nutritionist Cherilyn Lee has told interviewers that Jackson begged her for drugs. "He didn't take any medications from me, I'm just nutritional. When it switched over to medication, especially that particular medication, I told him -- I only deal with nutrition," she says. Records from her office have been taken to aid in the investigation into his death.

Dombrowski says that there was likely an error either in Murray's description or in the police's understanding of the medical jargon.

Another doctor, Dr. Scott Engwall of UC Irvine's School of Medicine, says that 50 milligrams of propofol is enough to cause someone to sleep for anywhere from 5 to 10 minutes, but not enough by any means to be a "lethal" dose. Engwall said in the case of Jackson, who had been taking the drug constantly, might not even doze off from a 50 milligram dose.

"I think it's not unreasonable that there is some part of this picture we still do not know," Engwall told the Times.

According to TMZ, someone of Jackson's body size would need about 400 milligrams of propofol to sleep for 8 hours, which would amount to 16 times the dosage that Murray claims he gave Jackson.

In addition, PEOPLE is reporting that during a search of Jackson's house, other drugs including marijuana and bottles both full and empty of prescription drugs were found.

Also in question is the timeline from the day of Jackson's death that was in the newly-unsealed documents. According to police, Murray found Jackson not breathing around 11 a.m., and did not call 911 until 80 minutes later. In that time, police say he made several phone calls for a total of 47 minutes.

Murray's attorney Ed Chernoff has released a statement disputing the timeline. The statement reads: "Much of what was in the search warrant affidavit is factual. However, unfortunately, much is police theory. Most egregiously, the timeline reported by law enforcement was not obtained through interviews with Dr. Murray, as was implied by the affidavit. Dr. Murray simply never told investigators that he found Michael Jackson at 11 a.m. not breathing."

For someone taking the amount of drugs Jackson was taking there was only one outcome as in Elvis Presley's case that is death. Jackson was emaciated, full of needle marks, and filled to the hilt with prescription medications no one killed Michael Jackson but Michael Jackson. The story that this guy was a great father considering he was being medically managed 24 hours a day is as bogus as the fairytales he enjoyed so much. Stop making this bizzare human being some kind of hero, he had issues with his skin color, sexuality, and his self esteem. Embrace him for what he was, a great entertainer not a great human being.

the intention of the drug was not to keep him under to 8 hours. It more likely was used as a downer, to put him in a relaxed state so that he could go to sleep, he's got a show to do so and he was probably working on his show all night and part of the morning so he's going to try and hit it, get a few hours, and then get ready for another all nighter. if that is the dose they found in his body it could most likely not have been what killed him, not being used to the work load or even being exhausted by the workload his heart could very likely have tripped, and sent him in to cardiac... he could have had a heart attack, when it comes to body parts, 50 ain't all that young anymore.

JACKSON WAS HIS OWN WORST NIGHTMARE HE GOT CAUGHT UP IN A WORLD HE CREATED FOR HIMSELF AND COULD NOT HANDLE IT. MANY STAR AND ICONS HAVE DONE THE SAME THING .ALL THAT FAME AND DONT KNOW WHAT TO DO WITH IT OR HOW TO HANDLE IT . NO ONE FORCED HIM TO TAKE DRUGS NO ONE FORCED HIM TO FONDLE LITTLE BOYS. AND ABOVE ALL NO ONE FORCED HIM TO CONTINUE A MUSIC CAREER. HE WAS 50 I WOULD HAVE GOT OUT OF IT AT 40. WITH MILLIONS IN MY POCKET

It wasn't the amount. It was the mixture of drugs that MD administered. The is absolutely no protocol for that mixture of drugs to be given to anyone, for any reason. He knew better...it was murder. Hope he lands in prison. It's a shame Michael Jackson died, just trying to get some sleep. If you can't sleep, it's miserable state of being.

"I met Michael Jackson when he was a small boy visiting his cousins on Kentucky ST.,in Gary,Ind. My daughter was having a birthday party and they all came over and sang and dance for her (they had no money for a gift)we never forgot the fun they all had that day. The same daughter died at age 41 of a perscription overdose given to her by her doctor,I couldnot believe the sad irony of thier deaths. No,attorney here would take my case. I feel these doctors play GOD with our childrens'lives. You have my most heart felt sympathy.Color has no name and only GOD has all the answers. GOD BLESS!"

May God bless you as well. Thank you for sharing such heartfelt story.

I'm a nurse who uses propofol in my unit. Propofol is a quick on (30-60 seconds onset) and quick off (wears off in minutes) unless given as a continuous infusion via an IV pump. If the good doctor pushed 25mg, MJ would go to sleep for about 5 minutes and then wake up. He's have to push alot more than 25mg to knock MJ out and knock out the respiratory drive. One would have to be an idiot to push it and think MJ would sleep for hours. The beauty of propofol is quick on/quick off, so there has got to be more to the story that what is being revealed. No matter what the story is, a cardiologist has no business prescribing/administering/possessing propofol. In my hospital, the cardiologists have no clue about using propofol. Something is very fishy....guilty, guilty, guilty.

Wacko Jacko,What you said was so wrong, on so many levels. You are entitled to your opinion, but don't be so darn harsh about it next time. Not many people appreciate it when you talk like that about someone that people cherished and looked up to as an artist. He was not guilty of anything besides being a great artist. So, get your facts straight before you try saying such lies because it just makes you look stupid.

It is a shame that people abuse the drugs giv en to them by the doctor and they do and no one forced them to take more then they should . It interesting how everone wants to sue the doctor yet it wasnt the doc that took to many. It says on the prescription bottle how many to take and if a person decides to take more and they die? It is their fault and not the doctors . So why should people be able to sue the doctor? I dont think this doctor killed Jackson, Jackson took other drugs before he got this drug that day and it interacted and it killed him. I think this whole thing is nothing but publicity to move his products, shirts records ect and this doctor is going to take the fall because the Jacksons lived of Mike and he is no longer here to support those people and they want to make an OD a murder case to bring in the money they need from Mike..one way or the other.

come on now the man faked his death why do you all think no charges will ever be filed or no autopsy will ever be revieled dj am died 2days ago they already have his why does it take that long for michael jackson's to come out come on people wake up and what takes two months to be buried now going on 3 and why do we only see that 1 pic of that damn doctor over and over again i swear thats the only picture he ever took but look at the fact people

Clyde, it was everything that killed him but the propofol in combination with everything else pushed him over the edge and his doctor(murray) is a jerk. Demerol can be reversed with other medications, however the is NO REVERSAL drug for propofol. And since Murray was not qualified to administer propofol and did not know how to do cpr or breath for Michael, that is why he died. If overdose of Demerol is given another drug can in a very short time reverse it.
